Reproductive success appears to increase with age in these animals, suggesting increasing fecundity with age . The insulin/insulin-like signalling pathway mediates life history trade-offs in mammalian model organisms. In contrast to mammals, IGF2 levels exceeded those of IGF1 in the mountain garter snake. IGF2 may play a more prominent role in postnatal growth and environmental sensing, a role IGF1 normally encompasses in placental mammals .
